Solution

The function of petiole:
-If you've eaten a celery stalk, you've eaten a petiole, the part of some plants that connects the blade of a leaf to its stem. In terms of their function, petioles play an important part in photosynthesis. They are also responsible for the dramatic way deciduous trees lose their leaves in the fall.
The function of veins in leaf:
-Veins provide support for the leaf and transport both water and minerals (via xylem) and food energy (via phloem) through the leaf and onto the rest of the plant.
